Volume access groups
Contributors Download PDF of this page
A volume access group is a collection of volumes that users can access using either iSCSI or Fibre Channel initiators.
By creating and using volume access groups, you can control access to a set of volumes. When you associate a set of volumes and a set of initiators with a volume access group, the access group grants those initiators access to that set of volumes.
Volume access groups have the following limits:
A maximum of 64 IQNs or WWPNs are allowed in an access group.
An access group can be made up of a maximum of 2000 volumes.
An IQN or WWPN can belong to only one access group.
A single volume can belong to a maximum of four access groups.
